STEAMcooklaav SPECIVFICATON forming part of Letters Patent No. 293,048, dated elruary 1881.

Application filed June 21, 1888. (No modehi To @ZZ whom, it may concern,.- Y

Be it known that I, HUDSON MAXIM, of Pittsfield, in the county of Berkshire and State of Massachusetts, have invented a new and Improved Steam-Cooker, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved steam-cooker in which vegetables, meats, dre. can be cooked very rapidly, and in which cooker the heat is thoroughly utilized and a minimum of the same is lost.

The invention consists in a steam-cooker constructed with a cooking-vessel and a steamgenerating vessel, the steam from which is carried through a pipe extending to and through the bottom of the .steam-generator under the samein the form of a spiral, or forward and backward alternately, and is iinally passed `through the bottom of the steam-generator,

its open end being in the bottom ofthe cooking-vessel, wherebythe steam will be conducted to the cooking-vessel and `will be highly superheated at the same time.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of" reference indicate corresponding parts in both the iigures.

Figure l is a longitudinal sectional elevation of my improved steam-cooker. Fig. 2 is a plan view of the same, parts being broken` to the outer surface of the vessel A at about one-third of its height from the bottom. A tube, C, extends from the bottom of the vessel B to the upper edge of the vessel A, and is provided at its upper end with a screw-neck, D,` on which a screw-cap, E, ts, which is provided with suitable packing, E. A short distance below the plane of the bottom of the vessel A the tube C or the vessel B is provided with awater-gage cock, F. A pipe, G, having 'a considerably smaller diameter than the tube C, extends from the top of the tube C to and through the bottom of the vessel B, and is then carried forward and back alternately in opposite directions across thebottom ofthe vessel B a short distance from the same, and is then above-mentioned pipe-layer, and is finally can ried through the bottom of the vessel B and to the bottom of the vessel, where it terminates at G, the end of the pipe being slightly flared and containing an upwardly-opening check-valve, H, which is held in place within the end of the pipe by a metal strip, J, secured to the upper surface of the bottom of the vessel A and eX- tending across the end of the pipe G. lf desired, a spiral only, or only the layer of pipe extending alternately "in opposite directions, can be arrangedA under the bottom' oi' the vesy sel B; for the layer of pipes extending alternately in opposite directions can be arranged adjoining the bottom of the vessel B1, and the spiral part of the pipe can be arranged below it.

I do not limit myself to any special arrange` ment of the pipes below the bottom of the vessel, but may arrange them in any manner to expose a great length of the pipe Gto the heat of the stove, lampburner, &c.

The cover K, which fits over the vessel A, is of such height that it extends down to the top of the vessel B. It is provided with an internal annular groove, L, on the under side of its top, along the circular edge, which groove contains a packingstrip, L', which rests against the upper edge of the vessel A when the cover is on the said vessel. The top of the cover contains a weight, M, to prevent the steam-pressure from raising the cover. The upper end of the pipe Gis bent downward, so that the water that is poured through the tube' C to fill the vessel B cannot pass into the pipe G. After the vessel B has been filled with water to the required height, the cooker is placed on the iire or over a lamp, Src., and the water in the vessel B is converted into steam, which rises in the tube'G, and then passes through the pipe G, in which it is superheated while passing through the coiled part or the part running in alternately opposite directions. The superheated steam then passes into the turned into a spiral between the bottom andthe.

vessel A and cooks` the articles in the same.

the sides of the vessel A. The packing L and the high sides of the cover prevent an undue escape of steam from the vessel A. The check- IOO valve H prevents solids or iluids eontainedin the Vessel A from passing into the pipe G, but permits'the superheated steam to pass freely in to the Vessel A. A

The cooker can be made an57 desired suitable size.

I do not abandon or dedicate to the public any patentable features set forth herein and not hereinafter claimed.

Having thus described my invention, I claimas new and desire to secure by Letters Patentl. rIlhe combination, with a steam-generator and snperposed cooking-vessel, of a pipe having a valved en d in the bottom of the cookingvessel, and an open en d inthe steam-space of the generator, carried down from the steam-space through the bottom, bent alternately iu opposite directions under said bottom, and passing through the generator into the cooking-vessel, as shown and described.

2. In a steam-cooker, the combination, with the vessel A, of the steam-generating vessel B below it, the tube C, extending upward from the vessel I5, and the pipe G, extending from the top of the tube C to the bottom of the -vessel B, under which it is coiled or passed alternatel y in opposite directions, and is then passed through the bottom of the vessel B to the bottom of the vessel A, substantially as herein shown and described.

3. In a steam-cooker, the combination, with the vessel A, or" the steam-generating vessel B, the tube C,extending upward from the bottom of the same, the pipe G, extending from the top of the tube C to and under the bottom of the vessel B, andup to the bottom of the vessel A, and the valve II in the end of the pipe G, substantially as herein shown and described.

4. In a steam-cooker, the combination, with the vessel A, of the vessel B, the tube C, the pipe G, the valve II, and the cross-strips J on the upper surface of the bottom of the Vessel A, substantially as herein shown and described.

In a steam-cooker, the combination, with the vessels A and B, of the cover K, provided with a groove, Landa packing-strip, Ii, and ofthe weight M in the top of the cover, substantially as herein shown and described.
